at station, the line climbed southwards on a significant gradient, with the steepest stretch at 1 in 45. The sharpest curve had a radius of . These factors combined to necessitate ruling speed limits of 20 mph for trains climbing to Dyserth and 25 mph back to the main line. These limits were lowered to 15 mph over level crossings and 10 mph approaching the junction with the main line. In practice the heavy loads, curves, visibility and gradients confined speeds to around 10 mph throughout. Passengers Toward the end of the Victorian era, and in the Edwardian period, tourism developed rapidly, and Dyserth Castle and the waterfalls at Cwm became important tourist destinations. In response, the LNWR started a passenger service on the branch from 28 August 1905, using a steam railmotor. The main line junction for the branch faced away from Prestatyn station, so that a train to the branch ran to the junction and reversed direction there on to the branch. There were two intermediate stations at first, with basic platform accommodation, but as residential development took place, additional halts were provided. At the start of the First World War a shuttle service was provided. In 1919 there were eleven journeys each way, on weekdays only. The railmotor services were popular, and from 1911 a trailer car was added to the formation. After 1919 auto-trains were brought in to replace the railmotors.

Decline and closure Although the train services were popular, road bus services were considered to be much more convenient by the mid 1920s. The last timetabled passenger train ran on 20 September 1930. Two enthusiasts' special trains traversed the line, the "North Wales Rail Tour" where a tank locomotive propelled three coaches to Dyserth on 2 October 1955 and "The Welshman" formed of a six car DMU on 11 October 1969. As goods and mineral traffic on the line declined, the branch was closed to general traffic on
